Is there any other setting i.e Built in variables. or any other setting that affects how the string "000" is converted to 0 automatically in windows and not in Unix.
Cannot recall, but ....... CONVFMT is somewhat related, but I could not get it working as expected.
Here's another scenario:
The above outputs "NO" for awk, nawk, /usr/xpg4/bin/awk and gawk [on Solaris].
The above outputs "YES" for all the awk's mentioned above.
This is somewhat strange, but doing 'man nawk' on Solaris:
Quote:
expr == expr Equal to
............. other expressions......
Each expression has either a string value, a numeric value
or both. Except as stated for specific contexts, the value
of an expression is implicitly converted to the type needed
for the context in which it is used. A string value is con-
verted to a numeric value by the equivalent of the following
calls:
A numeric value that is exactly equal to the value of an
integer is converted to a string by the equivalent of a call
to the sprintf function with the string %d as the fmt argu-
ment and the numeric value being converted as the first and
only expr argument. Any other numeric value is converted to
a string by the equivalent of a call to the sprintf function
with the value of the variable CONVFMT as the fmt argument
and the numeric value being converted as the first and only
expr argument.
Based on my examples, it seems like under Solaris the "context" of yje comparision is defined by the type of the LEFT expression.
Actually I just tried the same test under MKS's awk on Windows and does work the SAME as it does on Solaris. And also it behaves the same under Cygwin's awk and gawk under Windows as well - well, at least for the test scenarios I've outlined above.
Hi,
I need to be able to take an unsigned long value and convert it to a string that is separted by commas.
So for example, if i have the unsigned long value 1372516, I'm supposed to somehow get "1,372,516".
Can someone please give me the right direction to go about doing this? Thanks. (3 Replies)

Hi,
I would like to convert the output from awk function to date and print on the screen.
Example : echo "Start Date: May 24 2010" | gawk -F": " '{print $2}'
Output : May 04 2010
I want this to be converted to 2010/05/24
Can i use date function here and how?
Thanks,

Can someone explain whats happening here:
$ awk 'BEGIN {print (2.5 - 1)}'
1,5
2.5 - 1 is correctly calculated to 1,5 (using european locale)
$ echo "2.5" | awk '{temp = $1 - 1; print temp}'
1
If i now pipe the string 2.5 through awk it seems at it truncates 2.5 to 2?

awk
awk(1) General Commands Manual awk(1)Name
awk - pattern scanning and processing language
Syntax
awk [-Fc] [-f prog] [-] [file...]
Description
The command scans each input file for lines that match any of a set of patterns specified in prog. With each pattern in prog there can be
an associated action that will be performed when a line of a file matches the pattern. The set of patterns may appear literally as prog,
or in a file specified as -f prog.
Files are read in order; if there are no files, the standard input is read. The file name `-' means the standard input. Each line is
matched against the pattern portion of every pattern-action statement; the associated action is performed for each matched pattern.
An input line is made up of fields separated by white space. (This default can be changed by using FS, as described below.) The fields
are denoted $1, $2, ... ; $0 refers to the entire line.
A pattern-action statement has the form
pattern { action }
A missing { action } means print the line; a missing pattern always matches.
An action is a sequence of statements. A statement can be one of the following:
if ( conditional ) statement [ else statement ]
while ( conditional ) statement
for ( expression ; conditional ; expression ) statement
break
continue
{ [ statement ] ... }
variable = expression
print [ expression-list ] [ >expression ]
printf format [ , expression-list ] [ >expression ]
next # skip remaining patterns on this input line
exit # skip the rest of the input
Statements are terminated by semicolons, new lines or right braces. An empty expression-list stands for the whole line. Expressions take
on string or numeric values as appropriate, and are built using the operators +, -, *, /, %, and concatenation (indicated by a blank).
The C operators ++, --, +=, -=, *=, /=, and %= are also available in expressions. Variables may be scalars, array elements (denoted x[i])
or fields. Variables are initialized to the null string. Array subscripts may be any string, not necessarily numeric; this allows for a
form of associative memory. String constants are quoted "...".
The print statement prints its arguments on the standard output (or on a file if >file is present), separated by the current output field
separator, and terminated by the output record separator. The statement formats its expression list according to the format. For further
information, see
The built-in function length returns the length of its argument taken as a string, or of the whole line if no argument. There are also
built-in functions exp, log, sqrt, and int. The last truncates its argument to an integer. substr(s, m, n) returns the n-character sub-
string of s that begins at position m. The function sprintf(fmt, expr, expr, ...) formats the expressions according to the format given
by fmt and returns the resulting string.
Patterns are arbitrary Boolean combinations (!, ||, &&, and parentheses) of regular expressions and relational expressions. Regular
expressions must be surrounded by slashes and are as in egrep. Isolated regular expressions in a pattern apply to the entire line. Regu-
lar expressions may also occur in relational expressions.
A pattern may consist of two patterns separated by a comma; in this case, the action is performed for all lines between an occurrence of
the first pattern and the next occurrence of the second.
A relational expression is one of the following:
expression matchop regular-expression
expression relop expression
where a relop is any of the six relational operators in C, and a matchop is either ~ (for contains) or !~ (for does not contain). A condi-
tional is an arithmetic expression, a relational expression, or a Boolean combination of these.
The special patterns BEGIN and END may be used to capture control before the first input line is read and after the last. BEGIN must be
the first pattern, END the last.
A single character c may be used to separate the fields by starting the program with
BEGIN { FS = "c" }
or by using the -Fc option.
Other variable names with special meanings include NF, the number of fields in the current record; NR, the ordinal number of the current
record; FILENAME, the name of the current input file; OFS, the output field separator (default blank); ORS, the output record separator
(default new line); and OFMT, the output format for numbers (default "%.6g").
Options
- Used for standard input file.
-Fc Sets interfield separator to named character.
-fprog Uses prog file for patterns and actions.
Examples
Print lines longer than 72 characters:
length > 72
Print first two fields in opposite order:
{ print $2, $1 }
Add up first column, print sum and average:
{ s += $1 }
END { print "sum is", s, " average is", s/NR }
Print fields in reverse order:
{ for (i = NF; i > 0; --i) print $i }
Print all lines between start/stop pairs:
/start/, /stop/
Print all lines whose first field is different from previous one:
$1 != prev { print; prev = $1 }
Restrictions
There are no explicit conversions between numbers and strings. To force an expression to be treated as a number add 0 to it; to force it
to be treated as a string concatenate "" to it.
